pixelity vs chromatic
Chromatic shows you every diff.
Pixelity tells you which ones matter.
Chromatic pioneered visual review for Storybook. But in a world where AI ships most of the diffs, "a human approves every snapshot" doesn't scale — and it was never protection against the vibe-coded change that breaks checkout. That's the job Pixelity was built for.
| ▚ Pixelity | Chromatic | |
|---|---|---|
| Who reviews the diffs | ✓ AI triage pre-sorts every diff — intended · regression · noise, with rationale and confidence — and learns from your overrides. Humans only see real suspects. | A human reviews and approves every changed snapshot, every build. |
| Flaky diffs | ✓ Deterministic capture with a CI-enforced gate: 20 cold-start runs, 0 pixel drift, byte-identical. Flake is treated as a bug, not a setting. | Anti-flake heuristics and re-runs; noisy diffs still land in your review queue. |
| What gets tested | ✓ Any URL, any app flow, plus Storybook stories — one config. | Storybook-first; app-level coverage means writing interaction tests yourself. |
| E2E coverage | ✓ Generated for you: an agent crawls the app, infers real flows, and lands portable Playwright specs on a review branch. Selectors self-heal with proposals, never silent rewrites. | You write and maintain the tests. |
| Video proof | ✓ AI-narrated video of every changed flow — on the PR, in the gallery, auto-feeding your public changelog. Failures include the break on tape. | Static snapshots only. |
| AI-authored PRs | ✓ Blast-radius analysis maps the diff to affected features, runs only the minimal test slice, and blocks with a break video + suggested fix. | TurboSnap re-tests changed stories — scoped to Storybook, no app-level guard. |
| Lock-in | ✓ Portable Playwright always (generated specs run under stock `npx playwright test`). Open-core: Apache-2.0 CLI/Action, source-available server, self-hostable. | Closed SaaS; snapshots and workflow live in their cloud. |
| AI costs | ✓ Bring your own API key on OSS; managed inference only if you want the cloud. | — |
| Pricing model | ✓ Flat tiers (Free / Pro / Team). | Per-snapshot billing — costs scale with every build × story × viewport. |
Comparison reflects publicly documented Chromatic behavior as of mid-2026 — corrections welcome.
Keep the review workflow. Lose the review workload.
Point Pixelity at your app (Storybook included), and let the AI do the first pass — you approve only what's actually suspicious.
